Description of the Invention: [Technical Field] The present invention relates to an active device array substrate and a display device, and more particularly to a thin film transistor array substrate and an electronic ink display device. [Prior Art] The electronic ink display device was originally developed in the 1970s and is characterized by a charged ball in which one side of the ball is white and the other side is foggy. When the electric field changes, the ball will rotate up and down and present differently. colour. The second generation of electronic ink display devices was developed in the 1990s and is characterized by replacing the conventional pellets with microcapsules and filling the capsules with colored oil and charged white particles. The white particles are moved toward or downward by the control of the external electric field, wherein white particles are displayed when the white particles are upward (close to the reader direction), and are displayed when the white particles are downward (away from the reader direction). The color of the oil. In general, the currently common electronic ink display devices include a front plane laminate (FPL) and a thin film electrical crystal array substrate. The front panel typically includes a transparent cover, a transparent electrode layer and a layer of electronic ink material. The electronic ink material layer contains electronic ink and a carrier liquid. When the electric field between the respective halogen electrodes of the thin film transistor array substrate and the transparent electrode layer of the front panel is changed, the electronic ink moves upward or downward according to the direction of the electric field, thereby causing each element to exhibit different optical characteristics. . It is worth noting that 'in the manufacturing process of thin film transistor array substrate', it is often because of various factors, such as particle contamination or material not including 18322twf.doc/g substrate, which can include multiple connecting lines. The scan line in the same-昼素区. In one embodiment of the invention, each of the membranes is 'crystal' and corresponds to two data lines. In addition, a plurality of connecting lines are arranged, which are arranged in the word line of the tablet 2 == board. - During the ceremony, there is a four-film strip scan line and two data lines in each pixel area. In addition, the electric solar array substrate of the present invention may further comprise a plurality of connecting lines disposed in the region to respectively conduct scan lines or data lines in the same pixel region. The present invention further provides an electronic ink display device comprising mainly the above-described thin film transistor array substrate, an electron ink material layer, a transparent electrode, and a transparent cover. The electronic ink material layer is disposed on the halogen electrode of the thin film transistor array substrate, and the transparent cover plate is disposed on the electronic ink material layer. Further, the transparent electrode layer is disposed between the transparent cover and the layer of electronic ink material. Based on the above-mentioned 'the present invention, a plurality of thin film transistors are arranged in a single crystal region', it is possible to repair with a pixel repairing technique after the flaw is discovered, or even without repairing, an additional thin film transistor can be used. Maintain, hang, and have an automatic repair effect. In addition, due to the display characteristics of the electronic ink display device itself, the halogen electrode can cover the entire halogen region. Therefore, the present invention increases the number of thin film transistors or other wiring under the pixel electrode, and does not affect the pixel. The aperture ratio of 18322 twf.doc/g has an effect. The above and other objects, features, and advantages of the present invention will become more apparent <RTIgt; [Embodiment] Please refer to Fig. 1, which is a cross-sectional view showing an electronic ink display device of the present invention. The electronic ink display device 100 mainly includes a thin film transistor array substrate 110, a transparent cover 120, an electronic ink material layer 130, and a transparent electrode layer 14A.

The material of the electrode layer 丨4〇 is, for example, indium tin oxide, indium zinc oxide (IZO) or other transparent conductive material. Further, the 'electron ink material layer 13' is disposed between the transparent electrode layer and the halogen electrode 112 of the thin film transistor array substrate 110. The respective pixels of the electronic ink display device 1 can exhibit different optical characteristics by the electric field change between the respective pixel electrodes 112 and the transparent electrode layer 14A. In order to improve the flaw in the pixel, the present invention arranges two or more thin film transistors in a pixel region to improve the process yield. In order to explain in detail the features of the present invention, a plurality of embodiments will be further discussed below with respect to wiring and halogen structures on the thin film transistor array of the present invention.
